Difference Between ERW Pipe and Spiral Weld. However, spiral weld pipes are more expensive to produce than ERW pipes. They also tend to have more variability in the wall thickness, which can result in inconsistencies in the quality of the pipes. This, in turn, affects their suitability for use in specific projects.
